Definitions

  • Exemplary embodiments of the present invention relate to a device for regulating the pressure and/or mass flow of a gaseous or liquid fluid, which can be conveyed through a line, in particular for a space propulsion system.
  • Mechanical pressure regulators are typically used for regulating the pressure and/or mass flow of gases or liquid mediums in a space propulsion system.
  • An operating point such as a control pressure, is set during manufacture of the mechanical pressure regulator.
  • the components are often manufactured months or even years before the component is used in space. Subsequent changes in the operating point, in particular when the space component is already in orbit, are no longer possible or are possible only with considerable effort.
  • Exemplary embodiments of the present invention are directed to a device for regulating the pressure and/or mass flow in such a way that the device is improved in terms of design and function.
  • Exemplary embodiments of the present invention provide a device for regulating the pressure and/or mass flow of a gaseous or liquid fluid that can be conveyed through a line.
  • Such a device may be used, for example, in space propulsion systems of any kind in order to implement the supply of pressure to the mediums to be conveyed or for regulating the mass flow rates of mediums.
  • a combination of a first, piezoelectrically actuatable regulating valve and at least two second, magnetically actuatable regulating valves is provided for regulating the pressure and/or mass flow of the fluid.
  • the regulating valves are connected to each other and to a line input in such a way that in a nominal mode the pressure and the mass flow of the fluid in the line can be set by means of the at least one first regulating valve, and a connection or isolation of the first regulating valve with or from the line input can be produced by means of the second regulating valves. In an emergency mode the pressure and the mass flow of the fluid in the line can be set by means of the second regulating valves.
  • the device can be used, in general, in all such areas, in which high pressure levels at the line input are to be reduced to low pressure levels at a line output by means of the device.
  • the device of the present invention is based on an electric control of a plurality of valves.
  • the regulating of the pressure and/or mass flow of the fluid to be conveyed is achieved by a combination of solenoid valves and piezo valves.
  • Exemplary embodiments of the present invention employ the solenoid valves for both regulating and shutting off.
  • the operating point for example a control pressure
  • the setting of the operating point can take place when the device is used in a space propulsion system, even in orbit.
  • the ability to change the operating point allows for realization of various applications.
  • the device can be used in supplying pressure to electric, chemical or cold gas propulsion systems or for regulating the mass flow rate in electric drive systems.
  • An additional advantage of the device is that due to the high degree of tightness, which is achieved by means of the solenoid valves, it is possible to significantly extend the operating time in orbit, possibly even until the end of a mission.
  • the proposed device exhibits a longer and more efficient operation, a feature that is an economic factor for an operator of a space device.
  • This more efficient operation is due to the fact that in a conventional device the mechanical regulators are permanently isolated once a space component has been positioned, and a remaining propellant is pumped out with the residual pressure in the tank. As a result, the space propulsion system is not operated at the optimal operating points and consequently exhibits lower efficiency.
  • one of the second regulating valves is connected in series with the first regulating valve between the line input and the regulating valve. Another one of the second regulating valves is connected in parallel to the first regulating valve.
  • This design variant enables a “bypass” of the first regulating valve, if, for example, this first regulating valve can no longer be opened.
  • the tightness of the device can be enhanced in a targeted way by connecting in series a second regulating valve with the first regulating valve.
  • one of the second regulating valves is connected in series with the first regulating valve between the line input and the regulating valve.
  • Another one of the second regulating valves is connected in parallel to the series connection consisting of the first regulating valve and the one of the second regulating valves.
  • the first and the at least two second regulating valves are assigned to a regulating unit.
  • the regulating unit is connected to the line input by way of a supply unit.
  • the supply unit has at least one third, magnetically actuatable regulating valve for connecting or separating the regulating unit to or from the line input.
